Specification of Letters Patent. Application led April 15, 191.1.

serial No. 621,268.

To all whom z't may concern Be it known that I, ELMER J. MANN-ING, acitizen of the United States, and a resident of Janesville, in thecounty of Rock and State of Wisconsin, have invented a new and ImprovedAtomzer, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are:to pro- -videi an apparatus of the character menis. disclosed in thestructure illustrated in the accompanying drawings, in which likecharacters of reference denote correspondinparts in all the views, andin whichigure 1 is a perspective view of an atomizer constructed andarranged in accordance with the present invention; Fig. 2 is a verticallongitudinal section of the same taken on the median line, and showingthe lparts in contracted position; Fig. 3 is a vertical longitudinalsection, showing the parts distended preliminary to operation; Fig.l 4is a cross section taken on the line 4 4 in Fig. 2; and 5 is a crosssection taken on the line 5--5 1n Fig. 2.

To provide a convenient receptacle for the carriage ofcertainmedicaments in form to be administered at any time I have constructedthe tubular holder 10. At the bottom of the holder 10 I have introducedan air inlet tube 11, at the inner end whereof is provided a valvechamber 12. The valve chamber -12 is of usual construction to provide aseat for the ball valve 13. The valve 13 is moved to its seat by aspiral spring 14 which is suitably mounted in the chamber 12.

, The tube 11 has fonmed thereon a suitable screw thread to engage atapped perforation in the disk 15, which is tted within the tion 20 nearthe bottom 16 thereof. The partition 20 has erected thereon at thecenter thereof an air tube 21. The tube 21 is enlarged Where the samejoins the partition 20 to form the base 22. The base 22 is rovided witha screw thread upon whic is screwed the removable tube 23. The tube 2lis provided with a delivery orifice 24 at the end thereof, and the tube23 is provided with an orifice 25 at the end thereof, the two orificesbeing juxtaposed and alined. The delivery of the air from the tube 21across the space se arating" the orifices 24 and 25 and outwar throughthe orifice 25 forms a suction to draw the liquid containedv in 5guiding the holder 10. Thefwalls of the lower end of the holder 10 areslightly eularged, as seen in Figs. 2 and 3, and are turned to form ashoulder to rest against the nut 26 when the same is screwed to positionon the tube 19. The holder 10 is loosely mounted in the tube 19 torovide between the juxtaposed sides of t e said holder .and tube apassage for air entering the space between the nut 26 and the body ofthe holder 10. f

When in the operation of the invention the tube 19 is drawn downward tothe position shown in Fig. 3 of the drawings, the

-surrounding air is sucked through the space between the tube andrholder and into the body of the tube 19. The ed es of the disk 18 yieldreadil to permit t e air to pass into the body o the tube'19. When nowthe.

from the said chamber up through the tube 21, thence through theorifices 24 and 25 to the outer air. As stated, in. this action thesuction formedI by the rush of air from one to rounding the tube 30.

the other of the said oricesserves to draw upward the liquid A, and toatomize the same. The holder l0 is closed by a cap 27. The cap 27 isscrew7 threaded to register with threads formed on the outer end of thehead 28. Between the squared shoulder formed on the cap 27 and the headis a packing 29 adapted to form a water-tight joint at this point. Thecap 27 being removed, the holder 'l0 is filled with the liquid A, asshown in SFigs. 2 and 3 of the drawings. The cap 27 is provided with alcentral tube 30 which eX- tends downward into; the holder 10. Betweenthe tube 23 and the tube 30 is formed an air passage which serves toequalize the air pressure in the holder 10 and the outer atmosphere.This provision overcomes any tendency to form a vacuum in the holder 10above the liquid. It further `provides for equalizing the pressure ofthe air in the said holder should the same become heated to expand.'

yThe operation of the invention is as follows: When the liquid has beenlaced in the holder 10 and the parts are olded together, as shown in 2of the drawings, it will. be noticed that the apparatus may be carriedfreely in the pocket without fear -of the contents leaking therefrom. Ifthe apparatus be upturned so that the pro-truding end of the tube 23 bedepended, the liquid A will pass into the holder 1-0 to the end thereofhaving the cap 27 and sur- There being no opening of the tube 3.0 fromthe ca pV 27, the li uid is held in the space surrounding the l.saidtube 30. When it is desired to use the apparatus as an atomizer this isaccomplished by the operator grasping the holder 10, using the groove 32for that purpose, and then drawinfg outward the tube 19 to the positionshown in Fi 3 ofuthe-.drawings. The end 'of the tu e 23 is then in--serted in the mouth or nostril as the need requires, W en the operator,whlle steadylng the apparatus by his grasp of the head Y and cap formingthe groove 32 in the manner' stated, forces the tube 19 "in thedirection indicated by the arrow in Fig. 3 toward the closing'positionshown` in Fig. 2. As

stated, the air .which'has ybeen trappedlfinfA the tube 19 isby thisaction transferred V"to the chamber under the partition 20 and upwardthrou h the tube A21, and outward therefrom. t 'rough the orifices 24,and through the orifices -25 is emitted from the tube 23. The\suctioncaused by the passage of air between the two orifices in the' mannerdescribed exhausts the airzcontained infthe space between the two tubes21 and '23, drawin the medicated'liquid into-'the tube 23an into thepathof the air passing between the two orices,=from the 'orifice 25whereof the mixed air and medicament is voided as a vapor. i

`Having thus `described my invention, what I claim as new and desire tosecure by Letters Patent is 1.
